Help debugging PHP filter for wordpress [closed]

by

If you look at the codex entry for add_filter, you’ll see there are 4 arguments for the function, the last being $accepted_args, which should be an integer. Your add_filter calls are not correct, so I’m not sure how they worked in the first place.

There appear to be 5 arguments in your hooked function, so I presume your add_filters should be:

add_filter('gform_pre_submission_2', 'create_company_full_name', 10, 5);
add_filter('gform_pre_submission_1', 'create_company_full_name', 10, 5);
add_filter('gform_pre_submission_26', 'create_company_full_name', 10, 5);

That said, filters typically return a value, which your doesn’t, so I can’t say that’s correct either, as I don’t know Gravity Forms at all.
